If you think you'll co-sleep next time, don't bother with keeping it. We got a crib "just in case" from a yard sale. Our son has slept in it maybe four or five times? We're going to be getting rid of the crib and just replacing it with a toddler bed in our room since he's eventually going to sleep in that. The crib? He'll probably outgrow it before he'll be ready to stop co-sleeping and as much as we want to have another baby eventually, we'll probably co-sleep with that one too. The way we see it, if we find we need another crib, we can always buy a new one. We haven't needed a crib with any of our other kids, so we don't anticipate needing one in the future. There is also the possibility of getting a playpen for occasional use, which is what I did with my older three.
